Description

Technical Field

[0001] This utility model belongs to the field of mahjong machine technology, and in particular relates to a mahjong machine tile-raising structure. Background Technology

[0002] The working principle of a mahjong machine is that the mahjong tiles with their backs facing up are attracted by the magnetic ring on the shuffling drum, rotate with the magnetic ring and are sent to the conveyor trough, where they are pushed into a pile by the stacking motor at the machine head and pushed away by the chain rod. The tiles with their fronts not being magnetic continue to rotate on the plate (single-port machine principle), which has now been upgraded to a four-port machine.

[0003] A search revealed that application number 201720023876.7 discloses a linear lifting device for a mahjong machine, comprising a grid plate, a tile-lifting aluminum strip, and a lifting guide mechanism. This utility model employs a combination structure of a lifting shaft seat with a linear bearing and a steel lifting shaft. Through the linkage between the motor, gears, rocker arm, limit plate, tile-lifting aluminum strip, and lifting shaft, the lifting shaft can be freely controlled to move up and down along the guide hole of the linear bearing. It possesses technical advantages such as "achieving a tile-lifting opening in the panel that allows free control of the tile-lifting aluminum strip's up-and-down movement, greatly reducing the degree of shaking during the up-and-down movement, significantly improving the accuracy, stability, and work efficiency during lifting operation; and because the friction between the steel lifting shaft and the linear bearing is minimal, there is no need to add lubricating oil to the guide hole of the linear bearing, which increases service life, reduces costs, and is environmentally friendly."

[0004] However, existing lifting plates and limit plates all use thin sheet materials. In order to ensure strength, the thickness of the sheet material needs to be ensured, but the overall weight is heavy and the cost is high. Using thin sheet metal has poor strength. Adding triangular plate support after sheet metal is made can neutralize the weight, but the overall process is increased, including sheet metal, positioning, welding, and polishing of the welding position, and the cost cannot be effectively controlled.

[0005] To address the aforementioned issues, this application proposes a tile-raising structure for a mahjong machine. Utility Model Content

[0006] The purpose of this utility model is to provide a tile-lifting structure for a mahjong machine, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a mahjong machine tile-lifting structure, comprising a lifting plate and a drive plate connected to the bottom of the lifting plate via an adapter. The lifting plate is integrally formed from a horizontal top plate and a vertical guide plate, and the lifting plate has uniformly arranged honeycomb holes. The bottom of the top plate has reinforcing ribs. The adapter is fixedly connected to the bottom of the top plate, and a metal sheet is fixed to the bottom of the top plate by bolts. Two metal sheets are symmetrically arranged with respect to the adapter.

[0009] Furthermore, one side of the metal sheet is bent into a backing plate that abuts against the side of the reinforcing rib, and a plurality of second connecting holes are provided in the metal sheet. The lifting plate is provided with through holes that are installed with the second connecting holes by screws.

[0010] Furthermore, the adapter is integrally formed by injection molding, and connecting plates and side plates are formed at both ends of the adapter. A first connecting hole is formed in the connecting plate to connect with the top plate.

[0011] Furthermore, a groove is formed between the reinforcing rib and the top plate, and the metal sheet is installed in the groove. At least part of the metal sheet overlaps with the adapter seat, and the overlapping part of the metal sheet has a second connecting hole that communicates with the first connecting hole.

[0012] Furthermore, the adapter is fixedly installed with the lifting plate by means of screws engaging with the first connecting hole, the second connecting hole, and the through hole in the lifting plate.

[0013] Furthermore, the lifting plate and the adapter are integrally formed by injection molding, and a plurality of support plates are formed between the adapter and the guide plate, the support plates being perpendicular to the adapter and the guide plate.

[0014] Furthermore, the metal sheet has a notch for avoiding the connection between the adapter seat and the lifting plate.

[0015] This utility model has the following beneficial effects:

[0016] This utility model sets up an injection-molded adapter seat and a lifting plate. Various reinforcing ribs can be set in the adapter seat to ensure structural strength. At the same time, the weight and cost of plastic material are controlled compared with metal, while also ensuring the overall structural strength and durability.

[0017] This utility model features lightweight honeycomb holes formed on the inner side of the lifting plate, and a metal sheet at its bottom to strengthen the structural strength of the two ends of the lifting plate away from the adapter seat. It combines lightweight design with structural strength, and the metal sheet only requires threaded connection.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-6 As shown, this utility model is a mahjong machine tile-lifting structure, including a lifting plate 1 and a drive plate 3 connected to the bottom of the lifting plate 1 via an adapter 2. The drive plate 3 is connected to the adapter 2 in an adjustable manner, and the adjustment method is threaded. After adjustment, it is fixed by screws. The bottom of the drive plate 3 is connected to the drive end. Driven by the drive end, the tile-lifting mechanism moves up and down in the mahjong machine to achieve the purpose of lifting the tiles. The lifting plate 1 is integrally formed by a horizontal top plate 11 and a vertical guide plate 12. The side of the lifting plate 1 near the guide plate 12 is a tile-pushing mechanism, which works with the guide plate 12 to first arrange the tiles. After completion, the tiles are pushed onto the top plate 11 by the tile-pushing mechanism, and then the top plate 11 lifts the tiles to the table.

[0033] Furthermore, the lifting plate 1 is formed with uniformly arranged honeycomb holes, the honeycomb holes on the top plate 11 are located at the bottom and do not completely penetrate, and the honeycomb holes on the guide plate 12 are horizontally penetrating. The honeycomb holes can ensure structural strength while reducing weight.

[0034] Furthermore, the bottom of the top plate 11 is formed with reinforcing ribs 111, the adapter 2 is fixedly connected to the bottom of the top plate 11, and a metal sheet 4 is fixed to the bottom of the top plate 11 by bolts. Two metal sheets 4 are arranged symmetrically with respect to the adapter 2. The metal sheet 4 and the adapter 2 together form a reinforcing layer at the bottom of the top plate 11. This reinforcing layer can prevent the top plate 11 from bending and deforming, and ensure flatness.

[0035] Furthermore, one side of the metal sheet 4 is bent to form a backing plate 41 that abuts against the side of the reinforcing rib 111. The metal sheet 4 is horizontally set, and the backing plate 41 is bent downward, which can strengthen the vertical downward pressure resistance. At the same time, the abutment between the side of the backing plate 41 and the reinforcing rib 111 increases the connection tightness between the metal sheet 4 and the top plate 11. Moreover, the backing plate 41 only needs to be bent to form, which is simple to operate and low in cost. Several second connecting holes 42 are opened in the metal sheet 4, and through holes are opened on the lifting plate 1 that are installed with screws to the second connecting holes 42. Example 1

[0036] The adapter 2 is integrally molded by injection molding. The adapter 2 has connecting plates 21 and side plates 22 formed at both ends. The connecting plate 21 has a through first connecting hole 211 that connects to the top plate 11. The adapter 2 is fixedly installed with the lifting plate 1 by screws that cooperate with the first connecting hole 211, the second connecting hole 42, and the through hole in the lifting plate 1. In this embodiment, by coinciding with the first connecting hole 211 and the second connecting hole 42, the adapter 2 can be connected to the lifting plate 1 at the same time as the metal sheet 4 is installed, which simplifies the installation steps. In addition, the overlapping part can also increase the connection strength between the lifting plate 1, the adapter 2, and the drive plate 3, and reduce the risk of bending.

[0037] Furthermore, a groove 112 is formed between the reinforcing rib 111 and the top plate 11. The metal sheet 4 is installed in the groove 112. At least part of the metal sheet 4 overlaps with the adapter 2. The overlapping part of the metal sheet 4 has a second connecting hole 42 that communicates with the first connecting hole 211. In this embodiment, the connecting plate 21 is attached to the top plate 11, and the side plate 22 is set perpendicular to the connecting plate 21, which plays a role in structural reinforcement and prevents the connecting plate 21 from deforming and the adapter 2 from displacing after being compressed.

[0038] It is understood that this utility model uses an injection-molded adapter to connect with the lifting plate. By using built-in reinforcing ribs and plastic materials, it ensures structural strength and durability while controlling weight and cost. The inner side of the lifting plate is provided with lightweight honeycomb holes, and the bottom is reinforced by a metal sheet connected by threads, thereby achieving dual optimization of lightweight and mechanical strength.

[0039] A specific application of this embodiment is as follows: After the lifting plate 1, adapter 2, drive plate 3, and metal sheet 4 are formed, the two metal sheets 4 are first placed in the sink 112, and then the adapter 2 is connected to the bottom of the top plate 11. After the screw passes through the first connecting hole 211 and the second connecting hole 42, it is screwed and pressed tightly with the top plate 11, and the adapter 2 is connected to the lifting plate 1. Then, the metal sheet 4 is pressed and fixed to the lifting plate 1 through the remaining second connecting hole 42 by screws. Example 2

[0040] Please see Figures 7-8 As shown:

[0041] The lifting plate 1 and the adapter 2 are integrally formed by injection molding, and a plurality of support plates 13 are formed between the adapter 2 and the guide plate 12. The support plates 13 are perpendicular to the adapter 2 and the guide plate 12. In this embodiment, the integral injection molding of the lifting plate 1 and the adapter 2 can simplify the connection between the two, and at the same time ensure a reliable connection under the action of multiple support plates 13, which combines lightweight and structural strength.

[0042] Furthermore, the metal sheet 4 is provided with a notch 43 to avoid the connection between the adapter seat 2 and the lifting plate 1, so as to ensure the complete coverage of the metal sheet 4 at the bottom of the top plate 11 and avoid bending and deformation due to the low structural strength of the uncovered part.

[0043] One specific application of this embodiment is: the lifting plate 1 and the adapter 2 are integrally formed by injection molding, and then the metal sheet 4 is pressed and fixed to the through hole on the lifting plate 1 by screws through the second connecting hole 42.
